Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Modeling of the Resonant Inverter for Wireless Power Transfer Systems Using the Novel MVLT Method
Get PDFWireless power transfer (WPT) is a power transfer technique widely used in many industrial applications, medical applications, and electric vehicles (EVs). This paper deals with the dynamic modeling of the resonant inverter employed in the WPT systems for EVs. To this end, the Generalized State-Space Averaging and the Laplace Phasor Transform techniques have been the flagship methods employed so far. In this paper, the modeling of the resonant inverter is accomplished by using the novel Modulated Variable Laplace Transform (MVLT) method. Firstly, the MVLT technique is discussed in detail, and then it is applied to model a study-case resonant inverter. Finally, a study-case resonant inverter is developed and utilized to validate the theoretical results with MATLAB/Simulink
Opportunities and Challenges for Electric Vehicle Wireless Charging with Home
No full textDifferent problems arise to present time in power grid, distribution grid and smart grid causes when it comes to integrating electric mobility in a way that works well, grows, changes, and stays stable due to excessive load on grid. There is a way to solve the problem, by charging and discharging electric vehicles (EVs) with a two-way power exchange between EVs and grids and Home. To make these things fit into a clear plan for electric car use, this paper's main contributions are in the following areas: There are two types of power transfer: smart home-to-vehicle (SH2V), and vehicle-to-home smart (V2HS). Theoretical analysis further investigated by the MATLAB/Simulation to validate to grid interface with the EVs, and smart home through aggregator
A Self-Improved Optimization-Based Artificial Neural Network Model for WPT System for Electric Vehicle Charging
No full textRecently, research and development actions have been ongoing to overwhelm the issues with Electric Vehicle (EV) battery systems and long-distance driving limits. EV charging stations can be configured as wired and wireless, and their availability is growing. The EV parking spaces are designated for wired power transmissions where the batteries may be charged. The potential of electric sparks or other hazards makes wired charging of EVs unacceptable. Advancements in Wireless Power Transfer (WPT) in EVs demonstrate the capacity to transfer considerable power across short and mid-range distances. The main objective of this study is to predict the efficiency of the EV wireless charging technique. The accuracy of the WPT model in EV charging is increased in this research using the Self-improved Aquila Optimization Algorithm (SI-AOA) based Artificial Neural Network (ANN) model. The SI-AOA method is an enhanced version of the Aquila Optimization Algorithm (AOA), which is used to determine the weights of the ANN classifier most effectively. This strategy is suggested since it is efficient and time-saving. MATLAB/Simulink is used to model the suggested work, and simulation results are presented. In order to ensure the effectiveness of the envisaged approach, the results produced by the suggested model are compared to the results acquired by conventional methods in terms of error metrics
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
